Description

Technical Field

[0001] The present application relates to the field of fire fighting equipment, and in particular to a fire hose connector. Background Art

[0002] Fire hoses are hoses used to transport high-pressure water. Traditional fire hoses are lined with rubber and covered with flax braid on the outside, while advanced fire hoses are made of polymer materials such as polyurethane and have metal joints at both ends.

[0003] In the prior art, the fire hose is generally fixed between the main body and the machine body by tightening bolts, but this method does not fix the fire hose firmly. When used for firefighting, the high-pressure water flow in the fire hydrant enters the fire hose with a large impact force, which can easily cause the fire hose to fall off from the machine body, thereby affecting the normal use of the fire hose.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that fire hoses are easy to fall off, the present application provides a fire hose connector.

[0006] The fire hose connector provided in this application adopts the following technical solution:

[0007] A fire hose connector comprises an upper connector and a lower connector, wherein both sides of the outer wall of the upper connector are fixedly connected with fixed blocks, one side of the outer wall of the fixed block is provided with an installation groove, both sides of the interior of the fixed block are provided with a cavity, one side of the interior of the cavity is slidably connected with a fixing rod, one side of the outer wall of the fixing rod is fixedly connected with a limit plate, a spring is sleeved on one side of the outer wall of the fixing rod corresponding to the limit plate, and one side of the fixing rod is fixedly connected with a pull plate.

[0008] Preferably, the outer wall of the lower connecting head is fixedly connected with a connecting seat at one side corresponding to the fixing block, and the outer wall of the lower connecting head is rotatably connected with a fixing plate through the connecting seat.

[0009] Preferably, a plug hole is provided on the side wall of the fixing plate corresponding to one side of the fixing rod, and the size of the fixing rod matches the size of the plug hole.

[0010] Preferably, the upper surface of the upper connecting head is fixedly connected to the second connecting tube, the lower surface of the lower connecting head is fixedly connected to the first connecting tube, and a metal hoop is provided on one side of the outer wall of the first connecting tube and the second connecting tube.

[0011] Preferably, a threaded tube is fixedly connected to one side of the upper surface of the lower connecting head, and a threaded groove is provided on the inner wall of the upper connecting head corresponding to one side of the threaded tube.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The fixing rod is driven to move along the inner wall of the cavity by pulling the pull plate, and the size of the limit plate on the outer wall of the fixing rod is matched with the size of the cavity, so that the limit plate moves and the spring on the outer wall of the fixing rod is compressed. The fixing plate is rotated and inserted into the installation groove by rotating the fixing plate, and then the pull plates on both sides are loosened. The elastic potential energy generated by the compression of the spring pushes the limit plate to move, so that the fixing rod is inserted into the corresponding sockets respectively, and then the fixing plate and the fixing block are installed and fixed. Compared with the existing technology, it has the effect of preventing the upper connector and the lower connector from being disconnected due to excessive water pressure, and increases the firmness of the connection between the connectors.

[0020] The spring 15 on the outer wall of the fixing rod 9 is compressed by pulling the fixing rod 9, and then the fixing plate 8 installed on the outer wall of the connecting seat 7 is rotated to insert the fixing plate 8 into the installation groove 10. By loosening the pulling plates 12 on both sides, the elastic potential energy generated by the compression of the spring 15 pushes the limiting plate 16 to move, so that the fixing rod 9 is inserted into the corresponding jack 14 respectively, and then the fixing plate 8 is installed and fixed between the fixing plate 8 and the fixing block 6, so as to strengthen the connection between the upper connector 1 and the lower connector 2, and avoid the upper connector 1 and the lower connector 2 being disconnected due to excessive water pressure, so as to avoid the loosening between the upper connector 1 and the lower connector 2, resulting in water leakage.

[0021] Reference Figure 1 and Figure 3 The upper surface of the upper connector 1 is fixedly connected with the second connector 4, the lower surface of the lower connector 2 is fixedly connected with the first connector 3, the outer walls of the first connector 3 and the second connector 4 are both provided with metal hoops 5, the upper surface of the lower connector 2 is fixedly connected with a threaded tube 17, and the inner wall of the upper connector 1 is provided with a threaded groove 13 on the side corresponding to the threaded tube 17;

The size of 6 matches the size of the cavity 11, so that pulling the fixing rod 9 drives the limit plate 16 to move, and at the same time compresses the spring 15 on the outer wall of the fixing rod 9, and then rotates the fixing plate 8 installed on the outer wall of the connecting seat 7 to rotate and insert the fixing plate 8 into the installation groove 10, and by loosening the pull plates 12 on both sides, the elastic potential energy generated by the compression of the spring 15 pushes the limit plate 16 to move, so that the fixing rod 9 is inserted into the corresponding jacks 14 respectively, and then the fixing plate 8 is installed and fixed between the fixing block 6, so as to strengthen the connection between the upper connector 1 and the lower connector 2, and prevent the upper connector 1 and the lower connector 2 from being disconnected due to excessive water pressure.
